OCPPLab covers EV charging protocol testing from a single charger smoke test to high-volume load runs, from CPMS regression to OCPI partner-readiness checks.
We work daily with OCPP 1.6 and OCPP 2.0.1, including the OCPP 1.6 Security Whitepaper edition 2 extension. The platform models charger behavior, common implementation differences, and JSON Schemas published by the Open Charge Alliance.
We've built end-to-end OCPI 2.1.1 and 2.2.1 implementations covering the full module set — Locations, Sessions, CDRs, Tariffs, Tokens, Commands, ChargingProfiles, and HubClientInfo — including hub-mediated integrations.
Our load-testing infrastructure is designed for high-volume virtual charge point checks against a CPMS. We validate CPMS proxy paths, real-time authorization flows, and offline transaction replay under sustained load.
We maintain vendor-style charger profiles and hub-oriented roaming workflows so teams can rehearse likely integration behavior before field testing. The catalog grows as the EV charging market does.
Every claim on this site — every field name, every enum value, every status code — is checked against the authoritative OCPP and OCPI specifications. We'd rather link to the OCA or EVRoaming Foundation than paraphrase.
Hardware labs are slow, expensive, and don't scale. We built OCPPLab so engineering teams can validate firmware, CPMS releases, and roaming integrations from a browser without coordinating physical chargers.
OCPP and OCPI are open standards. We publish technical guides, reference content, and the OCPPLab blog so any team building EV charging infrastructure has the documentation they need — whether or not they're our customer.
We track the upstream specifications continuously. Our test suites and protocol behavior are kept current against:
Open Charge Alliance: OCPP specifications
OCPP 1.6, OCPP 2.0.1, and the OCPP 1.6 Security Whitepaper edition 2.
EVRoaming Foundation: OCPI specifications
OCPI 2.1.1 and OCPI 2.2.1 with the full reference module set.
Vehicle-to-charger communication for Plug & Charge and ISO 15118-20 V2G.
Roaming hub integration patterns, certification requirements, and OCPI / OICP routing.
